DataGridTemplateColumn Filter

[Daniel Vaughan]

I have defined a DataGridTemplateColumn shown below. How do I enable filtering in the user interface? The filtering control is not shown for DataGridTemplateColumns. I would have expected that I could define a FilterDescriptor, as I did for sorting and grouping, but no such property exists.

 

<grid:DataGridTemplateColumn Header="Device Serial"
           CanUserEdit="False" CanUserFilter="True" CanUserSort="True">
   <grid:DataGridTemplateColumn.SortDescriptor>
          <core:PropertySortDescriptor PropertyName="DeviceSerialNumber" />
   </grid:DataGridTemplateColumn.SortDescriptor>
   <grid:DataGridTemplateColumn.GroupDescriptor>
          <core:PropertyGroupDescriptor PropertyName="DeviceSerialNumber" />
   </grid:DataGridTemplateColumn.GroupDescriptor><grid:DataGridTemplateColumn.CellContentTemplate>
       <DataTemplate>
           <HyperlinkButton Content="{Binding DeviceSerialNumber}" Tapped="HandleSerialTapped" />
       </DataTemplate>
   </grid:DataGridTemplateColumn.CellContentTemplate>
 </grid:DataGridTemplateColumn>

Hi Daniel,

Thank you for the provided code.

The filtering functionality is not provided out of the box with the current implementation of the DataGridTemplateColumn. The FilterDescriptor could be used in order to filter the Grid. It should be set to the DataGrid itself not to the column. Please check the following article for more detailed information: DataGrid: Delegate Filter Descriptor. 

In order to enable filtering on the TemplateColumn in the user interface you can create a filtering control of your own. Please take a look at the following article from our help documentation how to achieve this: DataGrid: How to create custom filtering control. I have also attached a sample project that demonstrates how the custom filtering control could be visualized for the DataGirdTemplateColumn.

I hope this will help.

Thanks for your response. 

It doesn't really help though because I was able to deduce that a custom filtering control was possible.

It's a shame you don't provide this feature out of the box. To me it seems like a bit of an oversight, since you already support sorting that way.

Daniel

Hi Daniel,

We have a Feedback Portal for UI for UWP and it could be used for logging issues or feature requests. Currently the RadDataGrid.TemplateColumn doesn't provide filtering functionality out of the box. In this case you could make a request for this feature to be included in the DataGrid for UWP features set.

Let me know if you have any other questions regarding this.
